European Identity Infrastructure

Trust starts
with proof.

ProofingTrust develops the infrastructure to issue and verify verifiable credentials for the EUDI Wallet — interoperable across Europe.

What We Do

The new identity layer
for Europe is here.

The EU's digital transformation is anchored in self-sovereign identity. The EUDI Wallet regulation mandates that every European citizen will carry a verifiable digital identity — and every organisation must be ready to work with it.

EUDI Wallet

The European Digital Identity Wallet is the EU's flagship identity framework — a standardised, privacy-preserving digital wallet for every EU citizen. We make your organisation EUDI-compatible from day one.

Decentralised Identifiers

DIDs are cryptographic identifiers controlled entirely by their subject, with no central authority. We resolve did:web and support did:key out of the box.

Verifiable Credentials

A verifiable credential is a tamper-proof, cryptographically signed attestation — a licence, a diploma, an employee badge — that anyone can check instantly, without phoning the issuer.

🇪🇺

Built for the European Digital Single Market

ProofingTrust is designed from the ground up to support eIDAS 2.0 and the EUDI Wallet ecosystem — the regulatory backbone of Europe's digital identity future.

How It Works

Issue. Share. Verify.

Three roles. One trust layer. Zero central authority needed.

Issuer
Your organisation
  • Creates a credential offer
  • Signs with its key
  • Wallet collects it (OID4VCI)
via OID4VCI
Holder
End user / EUDI Wallet
  • Stores the credential
  • Selective disclosure (SD-JWT VC)
  • Presents on request
via OID4VP
Verifier
Relying party
  • Requests a proof (OID4VP)
  • Resolves the issuer
  • Verifies + applies policy
Trust Layer

We resolve the trust.

Checking a credential means two things: resolving who issued it, and deciding whether to trust them.

Our trust layer resolves issuer identity — via did:web or X.509 — and decides trust by policy, from a closed ecosystem you fully control to open, EU-interoperable trust.

Standards & Interoperability

Interoperability isn't
a claim. We test it.

We build on the EU's official specifications, test against real wallets and the OpenID conformance suite, and contribute fixes back to the ecosystem.

Flagship

OpenID OID4VP 1.0 Verifier — HAIP

Our verifier passes the official OpenID conformance plan for OID4VP 1.0 under the High Assurance Interoperability Profile — the full happy-flow plus the negative tests (invalid signatures, replayed nonces, wrong audience). Run against the OpenID Foundation's own test suite.

View the public conformance plan

Registered EUDI Relying Party

We're registered in the EU's official relying-party registry, with the access certificates that let a wallet trust our verifier.

Tested against real wallets

We test issuance and verification against third-party EUDI wallets, and report our findings back to the ecosystem — building in the open.

Roadmap

Where we are,
where we're going.

We're building in the open, on the EU's specs and pilots — one proven step at a time.

Done
  • OID4VP 1.0 Verifier — HAIP conformance passed
  • First closed-ecosystem deployment — Employee Access Attestation
  • Wallet interoperability tested (issue & verify)
Next
  • OpenID issuer conformance (mirror of our verifier)
  • Broader wallet coverage
  • EU Trusted Lists & qualified trust as the ecosystem matures
  • Hardware-backed keys (HSM) for qualified signatures
Exploring
  • Travel & mobility — reusable traveller identity
  • Driver's-licence verification for car-rental / mobility operators
  • Exploratory — we're monitoring opportunities in these sectors. No commitments yet.
🇪🇺

We believe in Europe's digital identity. We build on the EU's pilots and specifications, follow the official conformance programmes, and contribute back to the ecosystem.

Pilot Program

Run a pilot with us.

The EUDI Wallet is being proven across Europe in large-scale pilots — including travel & mobility. We help organisations design and test real credential flows on top of it, before it goes mainstream.

What a pilot with us covers
  • Needs analysis & use-case design — map your credentials, issuers and verifiers to the EUDI model.
  • Integration — connect issuance and verification to your systems via our dashboard and APIs.
  • End-to-end flow testing — real issue-and-verify flows, from offer to presentation.
  • Interoperability testing — validate against EUDI wallets and the relevant standards.
  • A trust model you control — a closed ecosystem to start, with a path to open, EU-interoperable verification.

Tell us your use case and we'll scope a pilot together.
